Slide Potentiometers are devices used to measure the linear displacement of a sliding electrical contact along a resistive element. The PTL45-19W0-104B2 is a type of Slide Potentiometer known as a slide wire mechanism, which consists of a fixed contact and a moving contact that slides along a track resistive element. When the sliding contact moves, it changes the resistance between the two contacts, which can be calibrated to provide a linear displacement feedback.

Application Field

The PTL45-19W0-104B2 is primarily used for angular position sensing, such as in your steering wheel for a car or a knob on an electronic device. It is also used for controlling the speed of a motor and other linear motion applications, such as in a throttle or positioner. Additionally, the PTL45-19W0-104B2 is often used in medical devices, such as in monitoring respiratory motion and ultrasound.

Working Principle

The PTL45-19W0-104B2 operates on the principle of electrical resistive position sensing. The mechanism consists of a track resistive element that can be variously shaped to form a desired position sensing range. The slide wire mechanism has two contacts: one fixed contact and one sliding contact. When the sliding contact moves along the track resistive element, the resistance between the two contacts changes. The change in resistance with displacement is then calibrated to indicate a linear displacement.

The PTL45-19W0-104B2 is a precision device with a high linearity and repeatability. The track resistive element is encased in a housing to protect it from dirt and contaminants. The device is highly resistant to shock and vibration, making it suitable for use in demanding applications. The PTL45-19W0-104B2 is also designed to have a very low hysteresis, providing consistent and reliable readings even under changing environmental conditions.

Conclusion

The PTL45-19W0-104B2 Slide Potentiometer is a precision device designed for linear displacement sensing applications. It is used in various applications, such as controlling the speed of a motor, measuring angular positions and monitoring respiratory motion. The working principle of the device is based on changes in resistance between two contacts when the sliding contact moves along a track resistive element.
